Web site PlanHQ walks you through the process of designing a business plan.

Business planning with PlanHQ is sort of a paint-by-numbers process, which makes it an especially useful resource for people interested in starting a business who don't know all that much about business. Not only does PlanHQ help you set up your business plan, but it also helps you keep an eye on your goals, team members, finances, and market. PlanHQ unfortunately does not have a free version, but they do offer a 30-day free trial, and you can export your business plan after that point. Premium plans range from $9-$49/month. There's a lot to PlanHQ beyond the basic business plan, but if you're looking to whip up a business plan in a month using the free trial, you probably won't use most of them. — Adam Pash
